IN A PERIOD of a little more than sixty years since the first flight of the Wright Brothers, man's exploration of three-dimensional space above the surface of the Earth has extended beyond the atmosphere. Spectacular and exciting events in this dramatic quest have been well publicized. Behind these milestones of practical flight have been less publicized achievements in scientific research, making such progress possible. Although the X-15 has had its share of newsworthy milestones, its contributions to scientific research have been a more essential and more meaningful part of the program from its inception. This semi-technical summary of the X-15 program is directed toward the less publicized aspects of its achievements.
The year 1964 marks the tenth anniversary of the inception of the X-15 flight-research program, the fifth year since the first X-15 flight. When the program was first approved, its objectives were clearly stated in terms of aerodynamic heating, speed, altitude, stability-and-control research, and bioastronautics. Although these objectives have been essentially accomplished, it now appears that the three X-15's may be flown for perhaps another five years, in a new role as test beds for fresh experiments utilizing the X-15 performance, which still offers more than twice the speed and three times the altitude capability of any other aircraft now in existence.
